Roxadustat alleviates nitroglycerin-induced migraine in mice by regulating HIF-1α/NF-κB/inflammation pathway.

Sensitization of central pain and inflammatory pathways play essential roles in migraine, a primary neurobiological headache disorder. Since hypoxia-inducible factor-1α (HIF-1α) is implicated in neuroprotection and inflammation inhibition, herein we investigated the role of HIF-1α in migraine. A chronic migraine model was established in mice by repeated injection of nitroglycerin (10 mg/kg, i.

Long noncoding RNA GAS5 impairs the proliferation and invasion of endometrial carcinoma induced by high glucose via targeting miR-222-3p/p27.

Long noncoding RNAs (lncRNAs) have been identified to be critical functional regulator in the human tumors, while the deepgoing mechanism by which lncRNAs modulates the endometrial carcinoma is still elusive. In this work, we found that lncRNA GAS5 was under-expressed in the endometrial carcinoma tissue specimens, especially these samples with type 2 diabetes mellitus. Besides, the aberrant under-expression of GAS5 was correlated with the advanced tumor stage as well as poor prognosis outcome.

Decreased expression of miR-184 restrains the growth and invasion of endometrial carcinoma cells through CDC25A-dependent Notch signaling pathway.

Endometrial carcinoma (EC) is one of the most common malignancies of female reproductive tract in developed countries. MicroRNA is frequently dysregulated in human cancers and acts a key regulator role in tumor cell growth and metastasis. The aims of this study were to investigate the roles of microRNA-184 (miR-184) in EC cells and to identify its potential molecular mechanism.

Value of counting positive PHH3 cells in the diagnosis of uterine smooth muscle tumors.

The diagnosis of uterine smooth muscle tumors including leiomyosarcomas (LMS), smooth muscle tumors of uncertain malignant potential (STUMP), bizarre (atypical) leiomyoma (BLM), mitotically active leiomyoma (MAL) and leiomyoma (LM) depends on a combination of microscopic features, such as mitoses, cytologic atypia, and coagulative tumor cell necrosis. However, a small number of these tumors still pose difficult diagnostic challenges. The assessment of accurate mitotic figures (MF) is one of the major parameters in the proper classification of uterine smooth muscle tumors.

Clinical experience of uterine tumors resembling ovarian sex cord tumors: a clinicopathological analysis of 6 cases.

Objective: To compare the clinicopathological features, diagnosis, treatment, and prognosis of two types of uterine sex cord-like tumors.

Methods: The clinicopathological features of four uterine tumors resembling ovarian sex cord tumors (UTROSCTs) and two endometrial stromal tumors with sex cord-like elements (ESTSCLEs) were analyzed retrospectively.

Results: All patients were premenopausal women.

Ovarian malignant mixed germ cell tumor with clear cell carcinoma in a postmenopausal woman.

Malignant germ cell tumors of the ovary are very rare and account for about 2-5% of all ovarian tumors of germ origin. Most patients are adolescent and young women, approximately two-thirds of them are under 20 years of age, occasionally in postmenopausal women. But clear cell carcinoma usually occurs in older patients (median age: 57-year old), and closely related with endometriosis.
